I was not really sure what they were asking for here, but these are my thoughts on the problem. First, I thought that since each color in pixels is assigned a number with the light colors assigned the lower numbers and the dark colors assigned a higher number that the photo would be dark if it was enlarged. Then I thought, no that is just a number assigned to a color and that it would not affect the color if the photo was enlarged. Finally, I thought that if a digital photo was enlarged enough that you would see each individual pixel. This solution seems too obvious, and since the text was dealing with matrices I thought there must be more. :?:
